manufacturers and Telcos can get input from users and CPE manufacturers
regarding the implementation of National ISDN. Among NIUFÕs successful projects
have been the IOC ordering codes. Their web page is at
http://www.niuf.nist.gov/ . See National ISDN.

NonlatchingLoopback - A
(relatively) simple method of implementing network loop-in. A nonlatching
loopback is initiated when four consecutive bytes of the specified loopback
code are received, remains in place as long as every other byte contains the
loopback code, and continues for a minimum of four bytes after receipt of the
last loopback code. Also see latching loopback.

NT1 -
"Network Termination Type 1". The termination at the customer
premises of an ISDN BRI circuit. The NT1 performs the role of line termination
of the "U" interface and Code/Decodes from the line's 2B1Q coding
scheme. The customer end of the NT1 interfaces using the "S" or
"T" interface. The NT1 is frequently part of the "Terminal
Adapter".
